Minimalism is actually a function of privilege, because you can afford enough stuff that you can choose to get rid of it and live a simpler lifestyle.
But yea, your stuff can end up owning you.
Even in that respect, I believe the PERCEIVED necessary quantity / variety of -Stuff- is greatly inflated.
Humans need water, food, a roof, a bed, and a toilet.
But modernity has extended all requisites of Life into Gildings. Whereby the FORM usurps function to appease the senses for pleasure.
Hedonism is the downfall of every empire, be it personal, or vast nations..
It is characterized by the pursuit of pleasure for pleasure's sake..
We've got keyboards, it works, Move the hell on..
--- Then the capitalist will come in and say, it's about the money, and we're rich.. Wh000tt
But look at it this way...
You, the customer, waste your time, working, to buy yet another iteration of a tool (keyboard) that you already own.
Now to fill this continuous wasteful demand, the Capitalist has to work to build the keyboard to sell to you..
IN THE END, EVERYONE, Including Both the Customer and the Capitalist has to WORK towards fulfilling a POINTLESS endeavor..
